Gravel and sand trucks, cargo trucks, cement mixers, sand tractor trailers and containerized trucks are included in the travel ban, while refrigerated haulers carrying perishable goods, oil tankers, and trucks used for government projects are exempted from the ban.

On July last year, Manila also passed an ordinance banning city and provincial buses without existing terminals in the city.

In the resolution, provincial buses with private terminals within the city are still allowed to enter but they cannot unload passengers along the road.

Buses coming from places such as Quezon City, San Juan and Makati are barred from entering Manila.

According to Moreno, the scheme has significantly brought down the number of buses traversing Manila.

He said they are now also looking at making similar restrictions on other transportation modes such as jeepneys and UV Express units.
